Work done by a student of 3 º ESO (15 years) for the area of ??Technology, within the multidisciplinary task for Mathematics and Technology Design and construction of surfboards at different scales. " Is the material with polyester resin covers the surfboard foam and its function is like the metal frame in concrete. Polyester resins obtained by reacting certain organic acids with a group of alcohols. The reaction that takes place is an esterification. Wow. This is the first time I enter this blog and leave me really impressed with the amount and quality of information you give on surfboards. I work for two years teaching surfing at various beaches in Spain and is not common to find such detailed data as well. To made of surfboards, are all within the same material (foam), because I read that some are you long polyurethane . . I leave here what I read and I entered the doubt! . . Chile-American brothers living in our country, Ryan and Kris Cabezas, professional surfers, are experienced manufacturers of boards waves. In his workshop Pichilemu, Cabezas Surfboards, produced three to five tables per day with polyurethane foam and fiberglass resin. The made to order designs and colors to taste. Catalyst. Is the hardening of the resin, the polyester is blended at 2% and the epoxy at 40%, percentages may vary somewhat by manufacturer. HOLA SOY DE PERU TO TAL and shapers Peruvians here are fed up and good! we now have the xtr epoxy, the classic, now there a parabolic that "flex" are on the rails. You can learn to surf on any table you like, but some surfboards are more appropriate than others. To increase the speed at which progress your learning to surf, you need to start with the correct table. Not start learning to drive in a Ferrari and not'll want to learn to surf in a Ferrari (You know what we mean!). As that culture is the anti-Ferrari in surfboard?. If you've ever been taught in a school of surf, you have a good idea of ??culture is the best board for a beginner. It is a soft table. Sometimes called "foam", these soft boards are ideal because the soft structure of polyurethane surfboard foam far implies that float, allowing the beginner to catch waves easily. Their dimensions ensure that they are very stable in water, making for the novice msfcil stand. The fact that they are soft on the tables makes them ideal for a surf school, where injuries are kept to a MINIMUM (including the fins on this design are somewhat soft. )The ideal length of soft surfboards for an adult is about 8 feet. A soft table about 6 feet is more appropriate for a child. However, although they are ideal for a surf lesson, soft boards are surely not the best buy tables for the adult who regularly surfs. In the majority of people are these tables are quickly sin, not the best buy for them. For small children who do not progress rapidly in the surf or surf adults only make once a year on holiday, are a great buy. A molded table is a table that is produced in a chain is an alternative economically producciny a surfboard foam fiberglass custom made. The table is made from molded polyurethane surfboard foam covered with thick fiberglass and is practically indestructible. As a result of its construction, molded table is much more heavier than a soft or table as a table. Weight reduces the performance of the table, which is good from the point of view of someone who is learning, the table is more stable in water. The drawback of these tables is in weight, which means they can strike a sudden blow. When using these tables have to pay attention to know where the table is if you download it and watch other people in the water. Shaped table is a popular choice as a beginner board and has more to offer the surfer medium soft tables because the time period in which an be used to learn in them is higher. Another important factor is molded tables that are in high demand and always retain a good resale value AFTER you've learned to surf with them, as others often try to find a used board. Soft boards are suitable for everyone as a first table and, because of its construction, the size of the table does not really matter. An eight-foot table is ideal for an adult, while a six-foot table is best for a child. The downside is that we are kids soon and someone who regularly surfs need a new table. The molded surfboards that last more soft and can lead to a surfer from a complete novice to be a surfer half without a new table. Also have excellent resale value when we are looking for a deal. Its main drawback is its weight and it is incredibly difficult to submerge. There is a problem with two tables: they are not very attractive. This is the reason why many surfers do not dare to buy even if they are great for beginners surfboards. . . .
