Can composite veneers break easily?

The correct answer is no. Composite veneers do not break easily or in the same way as porcelain veneers can break. Composite veneer can chip for a variety of reasons, most commonly biting and chewing on hard food or grinding and clenching teeth. But even if they do break, Composite veneers are usually easily repaired in one visit. This is not the same with porcelain veneers.
